Custom Open-Die Forged Rectangle Bars, Blocks, and Flats

Manufacturers across aerospace, oil and gas, power generation, and other industrial sectors rely on forged steel blocks when standard bar or plate stock cannot meet their strength or durability requirements. GL Forge has the equipment and material inventory to handle these projects, from single prototypes to large orders.

If you need custom rectangle forged bars or blocks for your application, contact GL Forge to discuss specifications, or request a quote to get started today.

Capabilities and Options for Custom Forged Blocks

GL Forge produces three main product types:

• Forged Rectangles
• Forged Blocks
• Forged Flats

Every block, rectangle, or flat we produce is custom-made to the specifications a project calls for. Thicknesses typically start at 1.5 inches, and finished weights can reach up to 4,000 lbs, though exact dimensions and weight limits vary by application, material, and shape. Our team works with customers early in the process to determine what's achievable for a given part.

Benefits of Open-Die Forging for Forged Steel Blocks and Rectangles

Open-die forging offers real advantages over plate or bar stock pulled straight from the mill. Because the steel is compressed and worked rather than simply cut to shape, the resulting grain structure follows the contour of the part. That structural difference translates into measurable performance gains:

• Superior strength compared to plate or bar stock
• Improved grain structure for better performance and longer service life
• Custom shapes and sizes that aren’t available in standard stock
• Less material waste, which helps control cost
• Better impact resistance for demanding applications

Material Options

Material quality matters as much as the forging process itself. GL Forge stocks a range of premium carbon, alloy, and stainless steel grades for custom forged blocks, giving customers options suited to corrosion resistance, high-temperature performance, or raw strength, depending on what the application demands. Forging materials we keep in stock include:

• 13-8 Stainless Steel
• 15-5 Stainless Steel
• 17-4 Stainless Steel
• 316 and 316L Stainless Steel
• Nitronic 50 Stainless Steel
• Carbon Steel (multiple grades available)
• Alloy Steel
• Nitralloy 135

Additional Manufacturing Services for Custom Forged Blocks and Bars

We also offer secondary services that refine the mechanical properties or tolerance requirements of a forged component. With these services in-house, we can keep your project on a single timeline instead of bouncing between vendors. Our secondary services for custom forged blocks include:

• CNC milling and CNC turning
• Quench-and-temper heat treatment for enhanced mechanical properties
• Ultrasonic testing
• Mechanical testing

Why Choose GL Forge for Rectangle Forged Bars and Blocks?

GL Forge supplies forged steel and stainless steel blocks, rectangles, and flats to customers across aerospace, oil and gas, power generation, mining, food processing, and press building and repair. Our full range of served markets is detailed on our Industries Served page.

As a privately-owned company, we're able to adapt to project timelines and specifications that larger forges often can't accommodate. Working with GL Forge means:

• Personalized service from a team that takes time to understand your application
• Fast lead times and flexible delivery options
• A wide selection of premium stainless, carbon, and alloy steels
• Support for prototypes and short production runs, not just large volume orders
• Custom sizing and design flexibility on every order
